The purpose and composition of the radio-photon components of the fiber-optic distribution system of reference signals of the decimeter wavelength range are described. The principle of the components of the fiber-optic distribution system of reference signals is described. The possibility of creating radio-photon components with improved technical characteristics in comparison with the closest foreign functional analogues has been proved. High technical characteristics are achieved by the original design and parametric compensation of the phase delay of the signal.

AbstractThis paper reports on research on the relationship between the electromagnetic scattering properties and physical properties of snow-pack. An FM-CW active microwave radar system operating in the frequency range 8-12 GHz is used to scatter electromagnetic radiation from surface and subsurface stratigraphic layers in the snow-pack. The amplitude of the scattered radiation as a function of depth in the snow-pack can be correlated with such physical characteristics as density, hardness, stratigraphy, and moisture content. A direct determination of snow-pack water equivalence can be made from these observations.
